Module Field.Slots

The parts a Kobalte field gives the Label, Description and Field_error inside it, as React Aria's field does: its label, which names its input, by label_id where it is given; its description, a <span>, which describes it; and its error message, a <span>, which it shows while it is invalid. <Parts label_id="name">...</Parts>, made by Field.Slots (struct let label = K.Label.component ... end).
